Subject: [KJ] [PATCH 23/39] net/svcsock: replace schedule_timeout() with 	msleep()


Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. The code, as is, is not wrong; however I see two reasons to
use msleep(): 1) consistency across the kernel; and 2) milliseconds are far more
human-comprehensible than jiffies.
